The Department of Defense, specifically the Department of the Army through the W071 Endist Portland office, is seeking qualified contractors to conduct spawning surveys of Spring Chinook salmon above Green Peter Dam in Oregon. The contract, which is a firm-fixed price for a duration of 12 months, requires the contractor to provide personnel, equipment, and materials necessary for conducting comprehensive surveys, including carcass sampling and the delivery of detailed reports. This project is crucial for assessing salmon abundance, distribution, and spawning behavior, particularly in Quartzville Creek and the Middle Santiam River, with results to be reported monthly to the contracting officer’s representative. Interested parties should contact Rattiya Oaks at rattiya.p.oaks@usace.army.mil or Justin Figueredo at Justin.F.Figueredo@usace.army.mil for further details, with a final report and presentation due by April 30, 2026.
